An astonishing headline reporting on new observations from a team led to Nikku Madhusudhan claims they’ve found ‘hints of life’ on a planet orbiting a dwarf star some 124 light years away. What’s going on? (1/n) www.bbc.co.uk/news/article... 🔭 🧪

Bullying at Cambridge University There's a long article in today's Observer about bullying at Cambridge University, which I encourage you to read, as it shows that the scale of the bullying problem in Cambridge is very worrying. I'll just emphasize a couple of things here. One is that Cambridge…

I tried to image the Palomar 5 globular cluster with a Seestar S50 for 3 hours. The cluster is the middle of this image and some of the faintest stars have Gaia G mags of ~17.5 and the right proper motions to be Pal 5 stars. 🔭

Great book review by @chanda.bsky.social about another disappointing physicist, Roger Penrose, who didn’t treat their family or female students well.

Spent 4 hours on NGC 4631 (top galaxy, aka Whale galaxy) and NGC 4656 (bottom galaxy, aka Hockey stick galaxy) with a seestar last night. The hook in NGC 4656 is due to an interaction with other galaxies in the group. 🔭

Today’s solar eclipse from the southern UK. It was taken with a seestar 50. I was very impressed how well it kept the sun centered in the timelapse! 🔭 youtube.com/shorts/f-wsa...

Paper day with a paper led by Connor Hainje: arxiv.org/abs/2503.15589. We studied how different the Sagittarius stream would look in self-interacting dark matter. In SIDM, ram pressure can evaporate Sgr's dark matter halo, leading to rapid mass loss, which changes the stream morphology. 1/ 🔭 🧪

I also got this nice image of the Orion Nebula. The framing options are quite nice on the seestar and are great for large objects on the sky. 🔭

I played a bit more with our department’s seestar and got this image of M3. The AIdenoise seems to pick out the stars resolved in the original image quite well. 🔭

Had some fun tonight learning how to use one of our department’s seestar telescopes. They’re super easy to set up and use. I think our students will enjoy imaging galaxies with these! 🔭

Farewell Gaia! It’s impressive how much we’ve learned from just 33 months of data and I can’t wait to see what else is hiding in the full data!

New submitted paper day! Led by @redshiftless.bsky.social, with me, @chrislintott.bsky.social, Simon Portegies Zwart, and four of the postgrad students in our group. We explore a beautiful new phenomena: what happens to interstellar objects as they drift out from their star & wander the Galaxy? 🔭🧪🧵
